A great reg combo for reliable and regular diving: the Halcyon H50D first stage and the Aura second stage regulator.
With Halcyon’s H50D, you get a balanced diaphragm first stage. It features an environment seal, which makes it suitable for extreme dive conditions, for example super cold water or contaminated environments. The high-performance diaphragm design is quite popular with cold water divers.
The simple, yet classic design makes the Aura a reliable and sturdy second stage. It is a great addition to the H50D first stage. It is a classic downstream valve second stage. With the Air Control Valve you can regulate the regs breathing performance. On top, you get Halcyon’s Comfort Mouthpiece for a super relaxed diving experience.
